High-harmonic generation from two weakly coupled molecules: a simple tight-binding model
A tight-binding dimer model shows that the laser polarization maximizing high-harmonic yield flips from molecular axes to the intermolecular axis at higher orders, with the flip order depending on coupling strength, and this behavior is already present in adiabatically following states.
